[0032] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.
[0033] Refer to Figure 1 、 Figure 3, an embodiment provided by the present utility model: an auxiliary feeding device for a processing fixture, including a bracket 1, which stably provides a fixing function for the entire device. The upper end of the bracket 1 is fixedly connected with a conveyor A3. All conveyors mentioned below are the same prior art. The conveyor is designed with fixed plates on both sides and multiple sets of rotatably connected rollers in the middle, which can convert the gravity of the fixture placed on it into the power to drive the rollers to rotate through the inclination of the conveyor, so that the fixture slides. The fixture to be fed is stored on the conveyor A3. When the conveyor A3 is installed, it needs to be inclined at a certain angle with the bracket 1, which needs to be adjusted according to the actual situation, so that the fixture placed on it will slide on the conveyor A3 due to the inclination and slide onto the conveyor B2. A blocking mechanism 7 is provided at the front end of the conveyor A3. The blocking mechanism 7 includes a baffle 701, which prevents the fixture placed on the conveyor A3 from rolling down due to the inclination before the conveyor B2 rises to dock. The bottom end of the bracket 1 is fixedly connected with a base 8, which stably provides a fixing function for the upper hydraulic rod 4 and the bracket 1. The upper end of the base 8 is fixedly connected with a hydraulic rod 4, which is prior art, so that the upper fixed platform 9 can be controlled to lift and lower. The upper end of the hydraulic rod 4 is fixedly connected with a fixed platform 9, which keeps the upper fixed conveyor B2 stable. The middle part of the inner side of the bracket 1 is fixedly connected with a conveyor C6, which can store the fixture transported from the conveyor B2. When the conveyor C6 is installed, it is inclined at a certain angle on the bracket 1, which needs to be adjusted according to the actual situation, so that the transported fixture slides through the conveyor C6 to the designated location. Fixed plates 14 are fixedly connected to both sides of the conveyor C6, so that the upper support plate 16 can only move horizontally inside the fixed plates 14. The upper end of the fixed platform 9 is hinged with a telescopic rod 11, and the expansion and contraction of the telescopic rod 11 will control the inclination angle of the conveyor B2. The upper end of the telescopic rod 11 is hinged with the conveyor B2. The upper end of the fixed platform 9 is fixedly connected with a baffle 10, which will block the fixture on the conveyor B2 to prevent the fixture from continuing to slide and falling out of the device. The rear end of the fixed platform 9 is fixedly connected with a trigger frame 13. When the hydraulic rod 4 is lifted, the trigger frame 13 will squeeze the elastic piece 703 on the blocking mechanism 7 to make the support rod 702 rotate. The conveyor B2 is hinged with the fixed platform 9 through a hinge plate 12. The upper end of the hinge plate 12 is fixedly connected with the rear end of the conveyor B2, and the lower end of the hinge plate 12 is fixedly connected with the upper end of the fixed platform 9. When the telescopic rod 11 extends, the conveyor B2 will tilt backward, and the upper fixture will slide towards the conveyor C6. When the telescopic rod 11 contracts, the conveyor B2 will tilt forward, and the fixture on the conveyor A3 will slide forward.
[0034] Refer to Figure 4 - Figure 6, a rotating shaft is fixedly connected to the inner wall of the fixing plate 14, and a gear 17 is rotatably connected to the outer wall of the rotating shaft to provide a stable effect for the rotation of the gear 17 at a fixed position within the fixing plate 14. A support plate 16 is slidably connected to the inner wall of the fixing plate 14 to stably provide a fixing effect for the correction plate 5 at the upper end of the support plate 16. A tooth groove 18 is formed at the lower end of the support plate 16, and the inner wall of the tooth groove 18 meshes with the outer wall of the gear 17, so that the sliding of the support plate 16 will drive the gear 17 to rotate. When the gear 17 is stuck, the support plate 16 will also be stuck. A button 15 is slidably connected to the inner wall of the fixing plate 14. There is a protrusion at the upper end of the button 15. Pressing the button 15 will push the clamping plate 19 to rotate. When the button 15 is released, the clamping plate 19 will push the button 15 back to its original position. A limit is provided at the rear end of the button 15 to prevent the clamping plate 19 from sliding out of the fixing plate 14 when it pushes the button 15. A clamping plate 19 is rotatably connected to the inner wall of the fixing plate 14. The upper end of the clamping plate 19 contacts the button 15 and will be pushed by the button 15 to rotate. A support is provided in the middle of the clamping plate 19 and is rotationally connected to the inner wall of the fixing plate 14. The clamping plate 19 is elastically connected to the fixing plate 14 through a torsion spring A20. One end of the torsion spring A20 is fixedly connected to the side of the clamping plate 19, and the other end of the torsion spring A20 is fixedly connected to the inner wall of the fixing plate 14. The upper end of the clamping plate 19 contacts the button 15, and the lower end of the clamping plate 19 is clamped with the gear 17. When there is no external force acting on the clamping plate 19, under the action of the torsion spring A20, the lower end of the clamping plate 19 will be clamped with the gear 17. When the gear 17 is clamped with the clamping plate 19, the gear 17 cannot rotate. When the button 15 is pressed, it will push the clamping plate 19 to rotate so that the lower end of the clamping plate 19 is disengaged from the gear 17. At this time, the gear 17 can rotate. The correction plate 5 is fixedly connected to the upper end of the support plate 16. The correction plate 5 will keep the downward-sliding fixture parallel to the conveyor C6 to provide a stable effect. An outer hinge group 24 is fixedly connected to the front side of the correction plate 5. The middle part of the outer hinge group 24 is rotatably connected to an inner hinge group 26. The inner hinge group 26 is fixedly connected to a movable plate 21 at the rear side. The outer hinge group 24 is divided into upper and lower parts and rotates with the inner hinge group 26, and a protruding part for annular sliding connection is provided at the connection to prevent disconnection. By rotating, the angle of the hinge between the correction plate 5 and the movable plate 21 can be controlled. The movable plate 21 will guide the fixture that slides off-center to slide towards the middle. The bottom of the outer hinge group 24 is fixedly connected to a hinge rod 25. The combination of the hinge rod 25 and the block 23 enables the outer hinge group 24 to rotate around the hinge rod 25 as the central axis to provide a stable effect. A pull rod 27 is slidably connected to the outer wall of the hinge rod 25. The bottom of the pull rod 27 is fixedly connected to a block 23. The outer wall of the block 23 is inserted into the inner wall of the outer hinge group 24, and the outer wall of the block 23 is inserted into the inner wall of the inner hinge group 26. The block 23 fixes the outer hinge group 24 and the inner hinge group 26 by being inserted into both the outer hinge group 24 and the inner hinge group 26 at the same time.The outer wall of the pull rod 27 is slidably connected to the inner wall of the outer hinge group 24. The upper end of the pull rod 27 is a pull ring that can be pulled, and the lower end is a hollow connecting rod. When the pull rod 27 is pulled to drive the clamping block 23 to move upward, the clamping connection between the outer hinge group 24 and the clamping block 23 will be released, and the outer hinge group 24 can rotate to adjust the angle between the correction plate 5 and the movable plate 21. The clamping block 23 is elastically connected to the outer hinge group 24 through a compression spring 22. One end of the compression spring 22 is fixedly connected to the upper end of the clamping block 23, and the other end of the compression spring 22 is fixedly connected to the upper end of the inner wall of the outer hinge group 24. The compression spring 22 pushes the clamping block 23 away from the inner wall of the outer hinge group 24. Pulling the upper end of the clamping block 23 will separate the clamping block 23 from the lower end of the outer hinge group 24. At this time, the angle between the correction plate 5 and the movable plate 21 can be adjusted. Releasing the upper end of the pull rod 27, the compression spring 22 will push the clamping block 23 downward to reconnect the clamping block 23 with the lower end of the outer hinge group 24 to provide a fixing effect.
[0035] Refer to Figure 2 , a support rod 702 is rotatably connected to the front inner wall of the conveyor A3. When the elastic piece 703 rotates through the support rod 702, the baffle 701 will be driven to rotate. The outer wall of the support rod 702 is fixedly connected to the lower end of the baffle 701, so that the support rod 702 provides a fixing effect for the baffle 701. The right end of the support rod 702 is fixedly connected to an elastic piece 703, so that the support rod 702 provides a fixing effect for the elastic piece 703. The elastic piece 703 is elastically connected to the conveyor A3 through a torsion spring B704. One end of the torsion spring B704 is fixedly connected to the left side of the elastic piece 703, and the other end of the torsion spring B704 is fixedly connected to the left side of the conveyor A3. So that without being affected by external forces, the baffle 701 is in a vertical state and the baffle 701 will block the sliding of the fixture to be processed on the conveyor A3. When the hydraulic rod 4 lifts the fixed platform 9, the trigger frame 13 will push the elastic piece 703 to rotate and drive the baffle 701 fixedly connected to the support rod 702 to rotate. At this time, the baffle 701 is in a horizontal state and the baffle 701 no longer blocks the fixture to be processed, so that the fixture slides from the conveyor A3 to the conveyor B2.
[0036] Working principle: When machining a fixture, it is necessary to transfer and load the fixture to be machined, so that the fixture to be machined is placed on the conveyor A3. The conveyor A3 will make the fixture slide forward, and the baffle 701 will prevent the fixture from sliding out of the conveyor A3. When the hydraulic rod 4 raises the fixed platform 9, the trigger frame 13 fixed at the rear end will make the elastic piece 703 rotate and drive the baffle 701 to rotate. At this time, the baffle 701 will no longer block the fixture, and the fixture will slide onto the conveyor B2. The baffle 10 connected to the front end of the fixed platform 9 will block the fixture from continuing to slide. The hydraulic rod 4 drives the fixed platform 9 to descend. At this time, the baffle 701 is reset under the push of the torsion spring A704 to prevent the next batch of fixtures from slipping. When the hydraulic rod 4 descends and aligns the conveyor B2 with the conveyor C6, the telescopic rod 11 is extended, and the inclination direction of the conveyor B2 on the fixed platform 9 will change, so that the fixture above slides from the conveyor B2 to the conveyor C6. The correction plates 5 arranged on both sides of the conveyor C6 will center the fixture sliding here and prevent it from deviating from the middle of the conveyor C6. The fixture will slide through the conveyor C6 to the place where feeding is required.
[0037] When machining different fixtures, it is necessary to adjust the distance between the correction plates 5 so that the sliding fixture can be guided to the middle. Pressing the button 15 will make the protrusion inside the button 15 push the clamping plate 19 to rotate. At this time, the lower end of the clamping plate 19 will be disengaged from the gear 17. The support plate 16 at the upper end of the fixed plate 14 can slide on the inner wall of the fixed plate 14. Sliding the support plate 16 can adjust the distance between the correction plates 5. Releasing the button 15, the torsion spring B20 will reset the clamping plate 19. The lower end of the clamping plate 19 engaging with the gear 17 will fix the gear 17, and at the same time fix the support plate 16 on the tooth groove 18 meshing with the gear 17. After adjusting the distance between the correction plates 5, it is necessary to adjust the angle between the movable plate 21 and the correction plate 5 according to the situation, so that the fixture sliding to the side of the conveyor C6 can be prevented from sliding out through the guidance of the movable plate 21. Pull the block 23 to disengage it from the inner wall of the outer hinge group 24. At this time, the movable plate 21 can be rotated to adjust the angle with the correction plate 5. Release the block 23, and at this time, the block 23 will be re-engaged with the outer hinge group 24 under the drive of the compression spring 22. When the outer hinge group 24 is engaged, the correction plate 5 will be fixed with the movable plate 21.
[0038] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features.
